Codename: Tenka

The Game Menu

Items to collect

Process Terminated

Some blocked path...

One of the first enemies

The exit of some tunnel

A room (no duh!)

Kill'em all!

Some sort of generator you have to destroy

...like this! :)

Main control room (nothing to do here)

Notice the flying shell and the three colors in the corner which show the keys you have collected

If you wonder what it is, it's a smiley on a dark wall.

The struggle to turn this guy...

...into this green blobby thing.
